Unlimited DRS makes no sense for the purpose it was introduced (in fact it IS unlimited in qualifying).
I'd personally love to see unlimited KERS but that would start sth like the engine wars (crazy money, tiny gain). However I do agree with you in some sense that the current KERS situation is far from ideal. The worst thing is it seems like running without it is still
better off due to aero/ballast advantages, something that was clearly detrimental to the technology in 2009. Realistically I'd like to see them doubling the power cap and removing the boost button by streaming in the power.
In the end everybody's got different views about where F1 should be heading. You in particular seem to incline to real world relevance, which frankly might not echo with every F1 fan.
I for one want a better spectacle, in terms of not seeing fast cars stuck behind much slower ones for 40 laps (and my the DRS seems to be working wonders for this!!!). Some people, particularly on this forum, might want to see keen technological competition on all fronts. Some might want a spec series so that we can judge the drivers and race engineers more accurately. Some just wants the "good ole times" back...
In the end it's a compromise so I think what we can only hope for, collectively, is for the obviously stupid
(e.g. KERS today IMO) regulations to improve / go away.
